Description

一种使用生物质燃料的仿真壁炉 技术领域
本发明涉及一种使用生物质燃料的仿真壁炉，尤其有关于一种使用由稻草、木屑、农作物秸秆等粉碎压制而成的小颗粒作为燃料并且具有高热交换效率的取暖用仿真壁炉。
背景技术
生物质燃料是由稻草、木屑、农作物秸秆等粉碎压制而成的小颗粒。生物质燃料作为一种新型的能源因其卫生、环保、高效、经济等优势已经开始逐渐获得广泛的应用。
仿真壁炉是一种常见的设备，可以只作为装饰使用，也可以具有取暖功能。具有取暖功能的仿真壁炉一般使用电能作为能量来源，但用电作为能量来源具有费用高，加热慢等主要缺点。如果使用生物质燃料颗粒作为能源，所面临的最主要的技术问题就是如何在传统仿真壁炉这个有限的体积内充分的完成热交换，降低燃烧后排出室外的气体温度，减少能量浪费现象。因为在传统的技术中，热交换主要是通过烟气排烟道完成的，如果要求热交换充分，排出的废气温度低，就只能增加排烟道的长度，这样就不可避免的要增加壁炉的体积。
 技术问题
本发明所要解决的技术问题是提供一种使用生物质燃料的仿真壁炉，该仿真壁炉既具有很小的体积又具有更高的能量利用率。
技术解决方案
为了解决这个技术问题，本发明提供了一种使用 生物质燃料的仿真壁炉 ，其使用生物质燃料颗粒，并包括一个可安放于地面上的本体。本体包括前部一个用于观赏的仿真电壁炉和后部一个用于能量交换的取暖炉；取暖炉包括一个燃烧箱和一个辅助设备箱。 燃烧箱内在靠近地面的底部容纳有一个燃烧 器，燃烧器具有一个燃料架板，一个沿燃料架板周边向上延伸的侧板，以及一个位于燃料架板下方的鼓风区，侧板在燃料架板上方围成燃烧区，燃料架板和侧板上开设有数个通风孔。燃烧器的上方设有一个热交换箱，热交换箱包括一个朝向仿真电壁炉方向的正面，一个与正面相对的背面，一个朝向地面方向的底面，一个与底面相对的顶面，一个第一侧面，以及一个与第一侧面相对的第二侧面。底面上正对燃烧器处开设有一个烟气进入口，第一侧面上开设有一个烟气排出口。在热交换箱内设有两列以上、每列两个以上贯穿正面和背面的散热筒，每两列散热筒之间都有一片竖隔板，每片竖隔板与热交换箱的顶面或底面之间形成有一条横缝，其中每相邻两片竖隔板上的横缝不同在顶面一侧或同在底面一侧；每两片竖隔板之间都有至少两片横隔板，每片横隔板与其两侧的竖隔板之间都形成有一条纵缝，其中每相邻两片横隔板上的纵缝不同在同侧的竖隔板一侧。 热交换箱的背面一侧设有一个与散热筒相联通的背面送风箱，热交换箱的正面一侧设有一个与散热筒相联通的正面送风箱，一个散热风机可以向背面送风箱内鼓风。 辅助设备箱内容纳有燃料输送机构和电气设备。燃料输送机构包括一个料斗，一条一端与料斗下方的出口相连通另一端伸入燃烧区中的送料筒，以及一条可转动的容纳于送料筒中的燃料螺旋推送杆。电气设备包括散热风机、一部驱动燃料螺旋推送杆的送料电机、一部可以向燃烧器内的鼓风区内送风的鼓风机、一台与热交换箱第一侧面上的烟气排出口相联通的抽风机、仿真电壁炉使用的光源和电机、电源、和一个电源开关。
有益效果
本发明所带来的有益效果是由于热交换箱内多列散热筒以及带有横缝和纵缝的竖隔板和横隔板结构，在有限的结构空间内烟气的排放通道也就是热交换通道的长度得到了显著的增加，这样在不增加甚至减小了体积的情况下，炉具的热交换效率得到了显著的提升，减少了能量的浪费。

如图 5 所示，辅助设备箱 20 内容纳有燃料输送机构 60 和电气设备 70 。燃料输送机构 60 包括一个料斗 61 ，一条一端与料斗 61 下方的出口相连通另一端伸入燃烧区 34 中的送料筒 62 ，以及一条可转动的容纳于送料筒 62 中的燃料螺旋推送杆 63 。电气设备 70 的电路图如图 7 所示，包括散热风机 71 、一台驱动燃料螺旋推送杆 63 的送料电机 72 、一台可以向燃烧器 30 内的鼓风区 33 内送风的鼓风机 73 、一台与热交换箱 40 第一侧面 45 上的烟气排出口 451 相联通的抽风机 74 、光源 202 、电机 208 、电源 75 、一个电源开关 76 和电源指示灯 77 。电源 75 既可以是交直流电源 751 ，也可以在交直流电源 751 上并联蓄电池 752 作为辅助电源。交直流电源 751 和蓄电池 752 均能够单独供电。电源开关 76 安装于辅助设备箱 20 之上，可以控制整个电路的供电。具体如图 1 所示，开关指示灯 77 也安装于本体 1 之上电源开关 76 附近，用来指示电源开关 76 的开合状态。
燃料 80 为生物质燃料，是由稻草、木屑、农作物秸秆等粉碎压制而成的小颗粒。
在使用时，使用者可以先在所需位置的地面上将本发明炉具的本体 1 摆放平稳，向料斗 61 内倒入燃料 80 颗粒。当使用者按下电源开关 76 后，开关指示灯 77 亮起，表示电源接通，炉具开始工作。此时送料电机 72 转动，驱动燃料螺旋推送杆 63 将燃料 80 颗粒送入燃烧器 30 中，燃料 80 颗粒在重力作用下落在燃料架板 31 上。此时，使用者可以用点燃的纸张或酒精棉球等将燃料架板 31 上燃烧区 34 内的燃料 80 点燃。也是在同时，鼓风机 73 开始向鼓风区 33 内送风，风通过燃料架板 31 和侧板 32 上开设的通风孔 311 进入燃烧区 34 ，为燃料 80 的燃烧提供所需的氧气。当燃料 80 燃烧到一定程度时会产生低浓度的甲烷气体，这些甲烷气体在鼓风机 73 产生的气流的作用下产生带有火焰的流动的高温烟气。这些高温烟气从燃烧器 30 上行，经热交换箱 40 底部的烟气进入口 431 进入热交换箱 40 ，在抽风机 74 的带动下最后经第一侧面 45 上的烟气排出口 451 流出热交换箱 40 。如图 5 中的箭头所示，烟气在热交换箱 40 内只能通过交错的横缝 483 和纵缝 491 单向迂回前行。在烟气的前行过程中，烟气中的热量将被各列散热筒 47 充分吸收，并散失在与散热筒 47 内部相通的室内空气中，完成热量的交换。
当需要停止燃烧的时候，使用者可以断开电源开关 76 ，开关指示灯 77 熄灭，送料电机 72 停止转动，鼓风机 73 停止。没有新的燃料 80 供给燃烧，燃烧区 34 内的燃料将很快燃尽，使用者即可打开箱门 11 ，清理从燃烧器 30 内落下的灰烬。燃料架板 31 的边缘部分可以向上偏斜有一定角度，在中部形成一片 低地。低地可以聚拢燃料 80 ，从而避免边缘燃料燃烧受热不充分产生黑烟。
